SendBufferMemory
Effective Version
MySQL 5.0.0
Restart Type: N
TCP transporters use a buffer to store all messages before performing the send call to the operating
system. When this buffer reaches 64KB its contents are sent; these are also sent when a round of
messages have been executed. To handle temporary overload situations it is also possible to define
a bigger send buffer.
The default size of the send buffer is 256 KB; 2MB is recommended in most situations in which it is
necessary to set this parameter. The minimum size is 64 KB; the theoretical maximum is 4 GB.

Effective Version
MySQL 5.0.0
Restart Type: N
This parameter is a boolean parameter (enabled by setting it to
0). It is disabled by default. When it is enabled, checksums for all messages are calculated before
they placed in the send buffer. This feature ensures that messages are not corrupted while waiting in
the send buffer, or by the transport mechanism.
